IMPROVEMENT Ili COTTON AND HAY PRESS.

dige .dgrinlr maar in in tigres trttrrs ininzt mit mating hat nxt tigttime TO ALL WIIOM IT MAY CON CERN Be it known that I, J. W. CONWAY, ofMadison, in the' county of Jefferson, and Stat-e ofVIndia-na, haveinvented an Improved Cotton, Hemp, and Hay Press; and I do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings, making part of thisspccication- Figure 1 being an end elevation of the press.

Figure 2 a side elevation thereof.

Like letters designate corresponding parts in both figures.

My improved press is constructed and arranged so as both to press andcompress the bale in succession, the same power being appliedalternately. The power is applied in a peculiar manner, so as to drivethe compressingfollower while the driver of the pressing-follower ismoving back, and oz'ee versa. The press is also so arranged that eitherhand power, with greater purchase, or horse power, with direct-leveraction, may be used at any time.

Lhave also a peculiar device for fastening the doors of thecompressing-box. Let A represent any supporting frame or foundation forthe press; B the pressing-box, placing horizontally; and C thecompressing-box, at one end of the pressing-box. The pressin{gf-followerD moves horizontally forward till it reaches the compressingfollowcrvF,and then it is retained in that position, (as in red lines, g. 2,) tillthe follower F descends vertically and compresses the bale. Inorder-that the pressing-follower D may thus remain stationary, and formone "side of the compressing-box, while the compressing-followerdescends, the said follower D is separate from its driver E, but fitsagainst it so as to he driven forward thereby in its proper uprightposition. Thon, as soon as it reaches the compressingsbox and follower,strong spring catches ai, one or more on each side ci' the box, springbehind the follower and prevent its return while the driver-E is drawnhack. By this arrangement Iam enabled to simplify the construction ofthe press, and econoinizc space, power, and time invoperating it; for,while the levers which drive the follower D are returning, Athey canresist in operating the follower F, and no time nor po rer will be lostin the work. And this use ofthe levers which operate the follower I), toassist in driving the follower F, obviates the employment of additionallevers for that purpose, and hence compaetness and simplicity ofconstruction are enhanced. The leverage for driving the follower D, andserving as the prime mover for the follower E, consists of thecombination of six levers, G, H, I, J, K, L, arranged substantially asrepresented in iig. 2. The first and last, G and L, are of the greatestlength; one end of cach is pivoted respectively to the driver E, and tothe fulcrum-bloclc M, and their contiguous ends are pivoted together.The next pair, J and K, are of half the length of the former-named pair,are pivoted at their upper ends respectively to the middle of said longlevers, and at their lower ends to cach other. The third pair, II and I,are of half the length of the preceding pair, J K, are pivoted at theirupper ends respectively, one to the lever Gat one-half the distance fromthe pivot of the lever Ithcrein to the lower end, and the other to themiddle of the lever J, while at their lower ends they are pivoted atonce to each other and to a fulcruin, V, secured to the frame orfoundation.

By drawing the ex treme outer end ofthe long levcrL inward toward thepressing-hog,- these levers are, as it were, shut together in au uprightposition, and the inner end ofl the lever G is corrcsp'ondently drawnoutward, thus drawing out the driver E of the follower D to the outerend of the pressingebox, as shown by black lines in fig. 2. But onextending thc lever L outward toward a horizontal position, the otherlevers are all extended in a similar' position, and consequently thedriver E, with its follower'D, is forced into the pressing box, asindicated by red lince in the same figure. 'lo operate these levers Ipropose either directly to draw the lever L inward and outward by thepower of a horse or horses, or to use manual-power applied upon a crankor wheel, I), on the shaft of which there is a pinion, Q, (shown indotted lines, iig. 2,) gearing into a sliding-rack, N, to which thefulcrum-bloek M of the lever L is attached. A pawl, O, takes into aratchet-wheel, 9,011 the shaftp of the driving-wheel l", to prevent-therack being pushed back by the elasticity of the cotton or hay if thopower is intermitted or slaclcened. The immediate operation of thecompressing-follower F is by means of a toggle-lever, R, anld bnr S, theformer pivotcd to the follower and to the lower end of the har S, aboutat the middle of its length, and the latter pivoted at its upper ond toa standard, e, ofthe frame. To move this toggle lever and bar by thelever system G, H, I, J, K, and L, a cord or rope, T, extends from theupper end of the lever R, first down around the shaftp ofthedrivingnvheel I, or around a pulley secured in a position near thesame, and thence up to a hook, t, on the lever G, as shown. When thelever Gis extended, as shown by red lines, in

operating the follower D, the rope T is siaekened and let out, thusallowing the follower F to rise; but when the lever G is raised, in thenot of drawing the follower-driver back, the hook t draws on the rope',l, and forces the follower F down, which thus compresses the bale.After the bale is bound and withdrawn, the follower D is freed from thespring-catches ol d, and pushed back to its driver E, (as shown by blacklines in lig. 2,) and the lid b of the pressing-box is raised forplacing another supply of the material to be pressed therein. The doorsc c ol' the compressing-box C have each a projecting-bar, forked ornotched in' the end where it projects, asv shown; and the two doors arefastened by a shaft, g, which has a T-shaped head, z', at each end. Theshaft g has a handle, 7L, which, when raised to a. horizontal position,(as shown by red lines in fig. 2,) brings the heads if.' also into ahorizontal position, coinciding with the notches in the barsff, so thatthe doors can then be opened. But when the handle h is dropped downward,(as shown by black lines in the same figura) the T-heads t'hold againstthe forks of the bars, and securely retain the doors closed. This deviceis very simple, and can be operated by a child.

What I claim as my invention, :ind desire to secure by Letters Patent,is

Both pressing and compressing the bales in one press, when the followersact alternately and by the same arrangement of leverage, but in reversemotions thereof, substantially as and for the purpose herein specified.

I also claim the detached follower D, arranged and operatingsubstantially as and for the purpose herein s'et forth.

I also claim the system of six levers Gr, I, J, K, and L, arranged andoperating in combination with the slidingwaok N, substantially as hereindescribed. y also claim the eombinationof the' lever system Gr, H, I, J,K, and L, and the toggle-lever and bar R S, through the medium of therope T, substantially as herein specified.

The above specification of my improved cotton andhay press signed by methis 21st day of May, 1866.
